Ryzen 3600 won't down-clock at idle

[Nanoray]

(Asus ROG Strix B450-F, latest BIOS, latest chipset drivers, Windows 10)

 

Just installed my new Ryzen 3600 and noticed that it is stuck at 4 GHz at all times and the CPU temperature continually "cycles" up and down, oscillating between high-30's and high-40's at idle. The vcore isn't locked but bounces around between 0.7 and 1.3+ V.

 

My old 2600 used to drop to 1.5 GHz and stay there at idle, with the voltage regularly living below 1V, and that's how I want my 3600 to behave.

 

All I have done in the BIOS is enable "global c-state control", set the RAM frequency to 3600 MHz, and set a -0.05 V undervolt - that's it. I haven't tampered with any clock speeds or other voltages or PBO or XFR or anything like that. I've been looking for a "Cool and Quiet" option but it doesn't seem to have one, and I've tried both Windows and Ryzen's "balanced" power setting with a 5% minimum setting.

 

Does anybody know how to get the 3000-series to downclock through the BIOS and/or Windows? I'm not installing Ryzen Master - I don't trust it.

What are you using to track this? Only Ryzen Master accurately reports clockspeed, voltage and temperature at idle.

 

EDIT: Other application will report the last load value - so they virtually cannot display idles at all - your system is working normally - ignore anything reported by other software than Ryzen Master

That's a shame, because it's the only software that reports clocks and core states accurately and overall is an actually good piece of software.

 

Aside from the VBS bug. That's ridiculous.

So you want an AMD CPU to run slower and act like an Intel CPU, and you don't want to run the appropriate utility because you're afraid of it? I don't think anyone is going to be able to help you.

Honestly though, get a better cooler, install Ryzen Master and enable PBO, enjoy 4.2ghz 24/7.

My ears - the fan is ramping up and down (even with smoothing enabled).

 

And CPU-Z - that's the only one that doesn't cause the "observer effect", I've read.

Cpuz is fery broken

 Have you properly updated the Bios and installed chipset drivers?

CPU-z also is pretty good for zen2 they updated it recently to use the Ryzen Master algorithms as well.

 

But that aside, there's no reason to stress over this... Frequency alone is meaningless if the CPU is idlying.

 

What is the windows power plant? If you are using stock cooler than you might have to adjust the fan curve manually on bios for best results as the 3600 does come with a relatively cheap cooler.

Better than an NH-D15?

I don't think you included that in your original post. I meant better than stock.

I use Ryzen Master as well but mostly Task Manager Performance Tab or MSI Dragon Center or CPU-Z. I have the X570 Gaming Edge Wifi, Ryzen 5 3600, a GTX 1660 Ti, and 16gb 3200mhz DDR4 RAM. Ive never seen the cpu idle below 4Ghz sometimes 3.96 but only for a second then back up to like 4076 Mhz. WHYY!!!!

Hello,
I really hope you guys were able to fix it so far, cause I had the same Problem when upgrading from my i5 6400 to i5 7600.
If not, please view my attached Screenshots for help to solve it.
Sorry that my system is on German, i tried to be quick with wrapping this post up, so i didnt mind changing my system language to english.
Please let me know, if it worked on your end.

post above might be onto something...

 

care to post your advanced power settings and also at what voltage is it running currently ? does it alternate,  if so between what figures?

 

 

just to be clear, thats not normal, ryzen should be downclocking to something between 2-3ghz *even if the readings aren't entirely accurate*

 

 

i would also suggest that whatever you did in BIOS has something to do with it and that you reset BIOS / load "optimized default settings " and dont touch anything then.
